Book Synopsis ESG nas relações de consumo by : Fabíola Meira de Almeida Breseghello
Download or read book ESG nas relações de consumo written by Fabíola Meira de Almeida Breseghello and published by Editora Singular. This book was released on 2022-11-18 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: "(...) Cada vez mais os consumidores se preocupam em adquirir produtos e serviços éticos, ou seja, que foram produzidos, anunciados e comercializados a partir dos princípios expostos no Pacto Global. Os produtos e serviços, na nova percepção dos consumidores, levam junto o contexto da sua linha de produção e comercialização. O livro, agora apresentado, enfrenta estes diversos problemas complexos, com análises fundamentadas e, muitas vezes, com sugestões para aprimoramento do próprio sistema. É a ciência cumprindo seu papel de trazer reflexões no intuito de melhorar as relações humanas. São 17 artigos que dão um destaque ao ESG no contexto do Direito das Relações de Consumo. Por óbvio, pela própria formação dos diversos autores – componentes do Comitê de Relações de Consumo do IBRAC (Instituto Brasileiro de Estudos de Concorrência, Consumo e Comércio Internacional) – os artigos enfrentam o universo das responsabilidades empresariais no contexto de uma sociedade de consumo.

Book Synopsis Sugarcane Bioethanol by : Luís Augusto Barbosa Cortez
Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.
Book Synopsis Guia Prático para Implementação de Agricultura de Precisão by : MAX EDITORIAL
Download or read book Guia Prático para Implementação de Agricultura de Precisão written by MAX EDITORIAL and published by Max Editorial. This book was released on 2024-04-14 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: O agronegócio vive uma era de transformação tecnológica, impulsionada pela Agricultura de Precisão (AP). Essa abordagem inovadora utiliza tecnologias para otimizar a produção agrícola, levando em consideração a variabilidade espacial e temporal do solo, das culturas e das condições climáticas. Este guia prático tem como objetivo fornecer aos produtores rurais um roteiro completo para implementar a AP em suas propriedades. Abordaremos desde as tecnologias básicas até a criação de mapas de manejo e a análise de cases de sucesso. Tecnologias para Agricultura de Precisão A AP se baseia em um conjunto de tecnologias que permitem a coleta, análise e gestão de dados georreferenciados da lavoura. As principais tecnologias utilizadas na AP são: •GPS: O Sistema de Posicionamento Global fornece a localização precisa de máquinas e implementos agrícolas, permitindo a navegação precisa e a aplicação de insumos em áreas específicas. •Drones: Aeronaves não tripuladas equipadas com sensores podem ser utilizadas para mapear a lavoura, coletando imagens aéreas em alta resolução para análise da saúde das plantas, identificação de problemas e monitoramento da produtividade. •Sensores: Diversos tipos de sensores são utilizados para coletar dados sobre o solo, as plantas e o clima, como pH, nutrientes, umidade, temperatura e índice de área foliar. •Softwares: Softwares específicos são utilizados para processar e analisar os dados coletados, gerar mapas de manejo e auxiliar na tomada de decisões. Criação de Mapas de Manejo A partir dos dados coletados, é possível criar mapas de manejo para diferentes aspectos da produção agrícola, como: •Fertilidade do solo: Os mapas de fertilidade indicam a variabilidade espacial dos nutrientes no solo, permitindo a aplicação precisa de fertilizantes, evitando desperdícios e otimizando a nutrição das plantas. •Irrigação: Os mapas de irrigação identificam as áreas da lavoura com diferentes necessidades de água, possibilitando a aplicação precisa de água e o uso eficiente desse recurso vital. •Manejo de pragas e doenças: Os mapas de manejo de pragas e doenças identificam as áreas com maior risco de infestação, permitindo a aplicação direcionada de defensivos agrícolas e o controle mais eficaz de pragas e doenças.

Book Synopsis The Root Causes of Biodiversity Loss by : Alexander Wood
Download or read book The Root Causes of Biodiversity Loss written by Alexander Wood and published by Routledge. This book was released on 2013-11-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.
